I feel the sound as not very good, he is rather tinny. Other products in this price range can convince as more.
The USB charging cable is not a good fit and can not be completely reingesteckt, so it wobbles around and it's just a matter of time before it destroys the socket.
Also worth mentioning are the sounds which can be played, for example, when turning on / off and when plugging in a cable. I feel as disturbing.
All in all it is a box that compared to alternatives should not be taken into consideration.
Packaging / Delivery / returning but easily and exemplary.
